(1) Enhance industrial manufacturing capacity and save energy and resources. At present, the development trend of seamless steel pipe reducing technology is more product varieties and higher steel pipe quality, which is not only reflected on the higher product dimensional accuracy but also the good

Forging steel: Pressure processing method that uses the reciprocating impact of a forging hammer or the pressure of a press to change the bank into the shape and size we need.Extrusion: It is a processing method in which the steel is enclosed in a closed extruder and pressure is applied at one end t

Anti-corrosion and thermal insulation pipeline construction When the anti-corrosion layer is constructed, the construction shall not be carried out without effective measures in rain, snow, wind and sand weather and environments with high relative humidity. The coating type anti-corrosion layer shou

There are several potential causes for the cracking of stainless steel welded tubes, including:1. Incorrect welding parameters: Welding stainless steel requires specific parameters, such as proper heat input and interpass temperature control. If these parameters are not followed correctly, it can le

ERW (Electric Resistance Welded) and EFW (Electric Fusion Welded) are two different welding methods used for producing welded tubes or pipes. The main differences between the two methods are as follows:1. Welding Process: ERW welding involves the use of a high-frequency electrical current to generat

The material commonly used for drilling casing is steel. Specifically, high-strength, corrosion-resistant steel alloys are often chosen for drilling casing to withstand the challenging conditions encountered during drilling operations, such as high pressures, corrosive fluids, and mechanical stresse

The OCTG (Oil Country Tubular Goods) casing running procedures typically involve the following steps:1. Preparing the rig and equipment: Ensure that the drilling rig is set up properly and all required equipment is in good working condition. This includes checking the elevators, slips, tongs, and ot

Cutting large diameter seamless steel pipes can be done using various methods. Some common cutting techniques for large diameter seamless steel pipes include:1. Sawing: A high-speed circular saw or band saw can be used to cut large diameter seamless steel pipes. These saws have large cutting capacit

Flange connection is an important connection method for pipeline construction.Flange connection is to fix two pipes, pipe fittings, or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fi

1. Concentric butterfly valveThe structural feature of this kind of butterfly valve is that the shaft center of the valve stem, the center of the butterfly plate, and the center of the body are in the same position. The structure is simple and the manufacturing is convenient. Common rubber-lined but
